- An uncooked gingerbread cookie is y centimetres long. After it is baked, the length of the cookie increases by 25%.
The initial length of the cookie is y after baking the length is increased by 25%
= y + 25%y
= y + ( 25 / 100 ) y
= y + 0.25 y
= 1.25 y
Therefore the expression best describes the new length of the cookie will be 1.25y.
